INNEBSOLE-APPL YING DEVICE.

Original No. 1,352,145, dated September 7, 1920. SeriaLNp. 335,538. filed November 3, 1519. Application for reissue filed April 17. mgtx- Serial No. 270,109.

This invention relates to devices of the class contemplated by the appended claims: the particular embodiment, hereinafter more particularly described. is a device for applyingthe inner sole to boots and slyo'tis.

One of the objects of this inve mio'fii is the production of a machine of this character in which the inner soles may bet forced by air pressure into contact with the inner face of the outer sole and retained in contact therewith until the. cement or other tacky substancehas set. Y3 v Another object is to provic a device of the class contemplated, in which a revolublc table mounted on a pedestal and having a plurality of shoe supportsthereon. each having a cooperating inflatable pad, has associated therewith 'air controlling' means whereby upon rotation of the table air is admitted to and exhausted from the pads.

-ln accordance with one embodiment of this invention the bearing: between the. pedestal and the table provides valve means; for com-rolling the supply and exhaust of air to and from the pads. For this purpose.

the pedestal part of the hearing has air sup-' ply and exhaust ports coupled with corresponding col'mections. While. the table part oi. the bearing has ports cooperating with those supply and exhaust ports and coupled with connections to the respective pads.

The ports leading to the pads are arrangedcircumt'erentially of the bearing, while the supply and exhaust ports are also spaced circiunfcrentially but so as to aline successively with the pad portsg. Accordingly upon rotation of the table. the padports are successivelyalined with the aunply port and til'iereat'ter successively aliped; witlrt'he eX- haust port. As each pad port alines with the supply. port, air will be admitted to the selected pad to inflate the same; this inflation of the selected pad will be maintained until the port leading'to that pad alines with the exhaust port when the pad will be deflated. This procedure takes place for each pad in succession, as the table isrotated. The bearing is preferably a tapered one so to provide a tight valve avoiding leakage of air.

In accordance with. one embodiment of this invention. each shoe support has a cooperating abutment. between which and the shoe support is arranged a cooperating inflatable pad. This abutment is arranged to be positioned or adjusted relatively its cooperating support and pad so as to permit placement of a shoe to be acted upon when the pad inflated and removal of the shoe when the operation completed.

'here the device is employed forthe application of an innersole to a shoe, then in accordance with one embodiment of this invention. the Shoe support has a chambered top in which is positioned an air receptacle adapted to be inflated after the shoe has been positioned upon said support.

The invention further consists in certain novel features of construction and arrange ment of parts which will be fully understood by reference to the description of the drawings and to the claims tube hereinafter givem For the'purpose of illustrating the inven'- 'tion one preferred form thereof is illustrated in the drawings, this form having been found to give satisfactory and reliable resuits, although it is to be understood that the 'various instrnmentalities of which the invention consists can be variously arranged and organized and the invention is not limit ed to the precise arrangementand organization of these instrumentalities as herein shown and described, except as required by the scope of the appended claims:

()t' the drawings: Fig. 1. represents a plan of a machine embodying the principles of the present in vcntion.

Fig. represents an elevation of the same,

with'parts thereof shown in section.

Fig. 3 represents a horizontal section on line 3, 3,011 Fig. 2.

Fig. at represents a plan of one of the shoe supports.

Fig. 5 represents a vertical section of the same on line 5, 5, on Fig. 4.

Fig. Grepresents a transverse section on line 6, 6, on Fig. 5 and,

Fig. 7 represents a transverse section on line 6, 6, on Fig. 5 with the bag inflated.

Similar characters indicate like parts throughout the several figures of the drawings.

In the drawings, is a pedestal adapted to be secured to the floor of a building.

This pedestal is provided at the top with a reduced cone-shaped projection 11 which fits into the cone-shaped socket 12 formed in the hub 13 of a rotatable table 14:. to provide a tapered bearing. forming valve means.

The periphery of the projection 11 has formed therein, a groove 15 extending partly around said projection and providing an air supply port, while between the opposed ends of said groove 15 is an exhaust port 16, this exhaust port 16 being in the same horizontal lane with the groove 15. I V

The hub 13 has a plurality of radial air passages 17 extending outwardlyfrom the socket 12 and in the same plane with the groove 15 and exhaust port 16. The passages 17 provide ports on the table part of the bearing adapted to cooperate with the ports 15 and 16 on the pedestal part of the bearing.

The peripheral groove 15 has an air\pas sage 18 extending therefrom the opposite end of which ciimmunicates with an. air inlet pipe or connection 19 in which is disposed a valve 20 to control the admission of air under pressure from any suitable source.

The exhaust port 16 has an air passage 21 extending therefrom, the lower end of'which rommunicates with a pipe or connection 22, extending outwardly through the pedestal. 10. all as indicated in Fig. 2 of the drawings.

Extending upwardly from the table 14 are a plurality of shoe supports 23 each of which has a depression 24 iii the top thereof, this depression 24 being. formed by a metal rim Q5 surrounding the upper end of the shoe support as clearly indicated in Figs. 4 and 5 of the drawings.

The toe end of the rimflfi hasan in turned ear 26 whieh engages a notclti in the toe end of the shoe support as indicated in Fig. 5 ofthe drawings.

The heel end. of the rim has a down wardly extending ear 27 through which extends a screw 28 threaded to the shoe sup-- port 23.

By displacing the screw :28. the'rim 25 may be removed from the shoe support 23 and another rim of different shape substituted therefor.

The upper edge :29 of the rim 2' is curved. as indicated in. Fig. 5 of the drawings, to fit the inner face of the outer sole of the shoe 30 shown in dotted lines in said Fig. 5;

i The top face 31 of the shoe support; 23 is preferably flat and preferably secured thercto by cement is an inflatable, pad 32, the edges of which are confined within the rim 25. The pad is prevented from expanding laterally by said rim 25.

he pad an opening 33 in the bottom thereof which communicates with a v'ertical air passage '34 extending the entire length of the shoe support 23.

The lowerendof each of the air passages 34 communicates with a pipe or connection 35 extending to a radial air passage 17 in the hub 13. p

Each shoe support 23 is provided with a vertical bearing 36 for a s'lidable member 37 having a head 38 formed thereon to limit' the" upward. movement of said member 37.

The upper end of the slidable member 37 has outwardly extending alined hubs 39 and surrounding the slidable member 37 between said hubs and the bearing 36; is a spring 40 which normally retains said slidable member 37 in raised position as indicated in Fig. 2 of the drawings.

Pivoted at 41 to the hubs 39 are two par allel arms 42, the outer ends of which have secured thereto a clamping plate or abutment 43.

The bearing 36 for the slidable member 37 is closed by a plate a4 having projecting therefrom, cars 45 to which is pivoted at 46 a pawl 47 adapted to engage the ratchet teeth 48 formed in one face of the slidable member 37.

The pawl 47 is provided with an arm 49 between which and the plate 44, is a spring 50 adapted to force the pawl 47 into engagement with the teeth 18.

In the operation of the machine, when a 'iplying an innersole to a shoe, an inner sole 51. with a tacky substance spread over its III) entire upper face is placed upon the pad 32 I as indicated in Fig. 6 of the drawings, this operation being performed while the pad 32 is deflated.

The shoe 30' is then positioned upon the full lines in Fig. 5 of the drawings. the

pawl 47 will be forced by the spring 50 into locking engagement with the teeth 48 of the slidablemember 37; i

The shoe is applied to the shoe. support which has its air passage 34: in comn'iunication with the exhaust port 16. \Vhen the shoe has been thus mounted upon the shoe support 23 and clamped thereto, the table 14 is moved in the direction of the arrow (1 on Fig. 3 of the drawings, until the passage 17 is in register with the perlpheral groove 15-.

. 100 support 23 as indicated in dotted lines in As soon as this passage 17 registers with the peripheral groove 15, air under pressure will be admitted through the pipe 19, groove and passage 17, to the pipe 35, and then direction of the arrow a on Fig. 3 of the port with the air supply port.

.taken off of the device.

drawings, the pad 32 will remain inflated and permit the cement or other tacky substance to firmly set.

When the passage 17 passes the end 52, said passage 17 will be closed and remain closed until the said' passage registers with the closed port 16 when the air within the inflated pad 32 will be permitted to escape and cause the deflation of said pad, the inner sole being firmly secured to the outer sole. 1 In practice the air will be retained in each pad for a period governed by the nature of the cement and the character of the work. Actually the operator will place a' P be turned so as to align that port with the air supply port thereby causingair to be admitted to the pad for inflating the same; the operator will then proceed to place a shoe on the next succeeding support and in cooperation with its pad and abutment, while that pad has its port in alignment with the exhaust port; the table is then again turned another step to align that pad This procedure is repeated for each shoe support, and by proper control of the operations, and

-with the required number of shoe supports,

the operations can be so governed that when an inflated pad again arrives at the exhaust port, the shoe will be in. condition to be When this has been accomplished, the

'shoe maybe removed from the support 23, a

new inner sole placed upon the deflated pad, another shoe placed upon the support, and the operation repeated.

'hile only four supports 23 are shown in the drawings, it is obvious that in practice a larger numberofsupports would be used.

The pad 32 may be made of rubber or any other material adapted to permit of the required expansioni This makes very effective device for applying inner soles to shoes which is simple in construction and easy to operate.

It is believed that the oper'ationot the iiivention and its many advantages-[will be readily understood without further descnip-vtion. r -1 Having thus described my invention, I claim:
